Modular cosmetic container

ABSTRACT

A modular cosmetic container comprises an outer case and an inner case which is pivotally disposed in a receiving space of the outer case and is provided with a containing space for placing cosmetic products. The upper surface of the outer case is a flat surface without any protrusion. An extending wall extending downwardly along the lateral side of the outer case forms a recess for retaining the upper wall of another outer case. Hence, a plurality of the modular cosmetic containers can be stacked and jointed together in the manner of lateral holdfast, such that the upper wall of one outer case is snugly fitted into the recess defined by the extending wall of another outer case.

BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention relates generally to a cosmetic container, andmore particularly to a stackable modular cosmetic container.

2. Description of the Prior Art

Two kinds of stackable cosmetic cases are described respectively in theU.S. Pat. No. 6,041,935 and No. 6,302,120. Two cosmetic cases have thesame stackable structure. A cosmetic case in the prior arts comprises anouter housing and an inner housing. The outer housing of the cosmeticcase is provided with a retaining protrusion extending along the uppersurface of the upper wall of the outer housing. The lower wall of theouter housing is provided in the underside with a retaining groove forretaining the retaining protrusion of the upper wall of another outerhousing. Therefore, a plurality of the cosmetic cases can be stacked andjointed together such that the retaining protrusion of one outer housingis snugly fitted into the retaining groove of the upper wall of anotherouter housing.

SUMMARY OF THE INVENTION

In view of the foregoing, a primary object of the present invention isto provide an improvement for the stackable structure of modularcosmetic containers which remove the retaining protrusion from the uppersurface of the upper wall of the outer housing.

According to the present invention, a modular cosmetic containercomprises an outer case and an inner case. The upper surface of theouter case is a flat surface without any protrusion. An extending wallextending downwardly along the lateral side of the outer case forms arecess for retaining the upper wall of another outer case in the mannerof lateral holdfast.

BRIEF DESCRIPTION OF THE DRAWINGS

The following detailed description of preferred embodiments of thepresent invention would be better understood when read in conjunctionwith the appended drawings. For the purpose of illustrating the presentinvention, there is shown in the drawings embodiments which arepresently preferred. In the drawings:

FIG. 1 is a top view of a modular cosmetic container of the presentinvention being opened.

FIG. 2 is a top view of a modular cosmetic container of the presentinvention being closed.

FIG. 3 is a sectional view taken along line A-A of FIG. 1.

FIG. 4 is a stackable schematic view of the present invention in use.

DETAILED DESCRIPTION OF PREFERRED EMBODIMENT

FIGS. 1 and 2 illustrate a top view of a modular cosmetic container ofthe present invention being opened and closed, respectively. In thepreferred embodiment of the present invention, a modular cosmeticcontainer with a cylindrical body includes an outer case 200 and aninner case 100. The outer case 200 is formed of an upper wall 206, alower wall 207, and a side wall 202 connecting the upper wall 206 andthe lower wall 207. The diameters of the upper wall 206 and the lowerwall 207 are identical. The upper wall 206 and the lower wall 207 areprovided respectively at predetermined corresponding positions with ahole for pivotally turning the inner case 100 as a center of rotation.

An open receiving space 201 for receiving the inner case 100 is definedby the upper wall 206, the lower wall 207, and the side wall 202. Theside wall 202 is provided at the edge side thereof with a retainingprojection 205 for locking the inner case 100. An extending wall 204 isformed on the lateral surface of the lower wall 207, so that the outerdiameter of the extending wall 204 is greater than that of the upperwall 206.

The inner case 100 corresponds in shape and size to the receiving space201 of the outer case 200. Additionally, the inner case 100 is providedwith a containing space 101 for placing cosmetic products, and isprovided at a predetermined position of the outer side wall thereof witha retaining recess 102 for engaging the retaining projection 205 of theouter case 200. The inner case 100 is provided at the lateral side witha curved projection 103 for easily releasing a lock of the inner case100 from the receiving space 201.

Referring to FIG. 3, the upper surface of the upper wall 206 is a flatsurface without any protrusion. The inner case 100 has upper and lowerends respectively provided with a pivot 104 for insertion intorespective holes 203 on the upper wall 206 and the lower wall 207. Theextending wall 204 extending downwardly along the lateral side of thelower wall 207 forms a recess 208 below the lower wall 207.

FIG. 4 illustrates a stackable schematic view of the present inventionin use. Two modular cosmetic containers can be stacked and jointedtogether in the manner of lateral holdfast, such that the upper wall 206of outer case 200 of lower container is snugly fitted into the recess208 defined by the extending wall 204 of outer case 200 of uppercontainer.

Although the present invention has been described in considerable detailwith reference to certain preferred embodiments thereof, those skilledin the art can easily understand that all kinds of alterations andchanges can be made within the spirit and scope of the appended claims.Therefore, the spirit and scope of the appended claims should not belimited to the description of the preferred embodiments containedherein.
